Red-eared slider turtles (Trachemys scripta elegans)

Morphological and mechanical changes in juvenile red-eared slider turtle (Trachemys scripta elegans) shells during ontogeny.

Turtles experience numerous modifications in the morphological, physiological, and mechanical characteristics of their shells through ontogeny. Although a general picture is available of the nature of these modifications, few quantitative studies have been conducted on changes in turtle shell shape through ontogeny, and none on changes in strength or rigidity. This study investigates the morpho...

Hormone levels in yolk decline throughout development in the red-eared slider turtle (Trachemys scripta elegans).

This study investigates the potential effects of maternally derived hormones present in the yolk of reptile eggs. Specifically, we ask when are these hormones utilized by developing red-eared slider turtles (Trachemys scripta elegans), a species with temperature-dependent sex determination (TSD). Eggs were incubated at 27 degrees C, a male-producing temperature, and at 31 degrees C, a female-pr...

Effects of exogenous corticosterone on locomotor activity in the red-eared slider turtle, Trachemys scripta elegans.

We investigated the effects of exogenous corticosterone on the locomotor activity of captive red-eared slider turtles, Trachemys scripta elegans. An increase in plasma corticosterone often increases locomotor activity in mammals and birds, but there are no reported findings for turtles. In this study turtles implanted with corticosterone-filled Silastic((R)) implants showed a significant increa...

Consensual pupillary light response in the red-eared slider turtle (Trachemys scripta elegans)

Purpose of this study was to determine if the turtle has a consensual pupillary light response (cPLR), and if so, to compare it to its direct pupillary light response (dPLR). One eye was illuminated with different intensities of light over a four log range while keeping the other eye in darkness. In the eye directly illuminated, pupil diameter was reduced by as much as approximately 31%. In the...
